Description
Technical field
The utility model relates to a kind of waterproof construction of battery management system slave shell.
Background technology
Along with worldwide energy crisis and environmental pollution, electric automobile has entered into people's sight line gradually.Lithium battery has also obtained development rapidly as several electrokinetic cells of current known the best, and is also very rapidly as the development of the battery management system of one of lithium cell electric automotive battery system important component part.Battery management system can extend greatly the life-span of lithium battery system and improve its applying working condition has been admitted facts.How to improve the reliability of battery management system, extend its useful life, reduce the importance that failure rate also becomes battery system stability study.Battery management system is mainly comprised of several slaves (BMU) and a main frame (CCU), and slave is generally placed in battery case.Due to the restriction of installation site and mounting means, the operational environment of slave is comparatively severe, operating temperature range wide (20 ℃ ~ 60 ℃, unsteady to some extent according to the region difference of Vehicle Driving Cycle), and often within a short period of time acute variation.In this case, airborne steam can be because the variation of temperature and at wire harness and BMU case surface a large amount of condensed water that freeze-outs, these condensed waters are flowing into behind BMU inside along wire harness and shell, can cause short circuit and the etching electronic element of BMU inside, when serious, can cause BMU to lose efficacy, battery management system paralysis.
Present most battery management system waterproofing design is all to adopt the mode of encapsulating that whole shell is shut completely, to stop above situation, occurs.But the way that encapsulating is shut can affect the maintenance of battery management system and the maintenance of firmware upgrading, some original paper on battery management system is because of after misoperation burns or damage, the method that just cannot damage element by replacing is repaired, can only scrap the management system of damage, integral replacing, can cause a large amount of wastes and the increase of cost like this.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of waterproof construction of battery management system slave shell.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the waterproof construction of battery management system slave shell, comprises housing, cap and connector; Cap is connected with housing, and the contact-making surface being connected with housing on cap is provided with a circle groove, and groove is embedded in waterproof apron; Connector is connected with housing, and junction seals with silicone grease.
Preferably, the junction of housing and connector is provided with the groove of filling sealing silicone grease.
Another preferably, the junction of housing and cap is provided with for spacing concaveconvex structure, must not relatively move after housing is connected with cap.
Also have one preferably, cap is provided with the PCB fixed leg of circuit board stretching out downwards.
The beneficial effects of the utility model are:
By the improvement to original battery management system slave shell waterproof construction, waterproof sealing effect is good, and extend useful life, has improved the fixed form of PCB circuit board simultaneously, make the installation and removal of PCB circuit board more convenient, and strengthened the structural strength of top cover.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the overall structure schematic perspective view of the waterproof construction embodiment of the utility model battery management system slave shell.
Fig. 2 is the front view of the waterproof construction embodiment of the utility model battery management system slave shell;
Fig. 3 is the vertical view of the waterproof construction embodiment of the utility model battery management system slave shell;
Fig. 4 is the cap interior views of the waterproof construction embodiment of the utility model battery management system slave shell;
Fig. 5: the housing and the cap partial view that are the waterproof construction embodiment of the utility model battery management system slave shell;
In figure: 1-housing, 2-connector, the anti-horizontal plane of 3-, 4-PCB fixed leg of circuit board, 5-housing fixing hole, 6-housing groove, 7-waterproof rubber gasket, 8-bolt, 9-cap.
Embodiment
As Figure 1-4, housing 1, cap 9 and connector 2 and waterproof rubber gasket 7 form a complete battery management system waterproof case.In Fig. 2, the upper limb of the upper limb of housing 1 and connector 2 forms the anti-water surface in same level, after installing, relies on bolt 8 that housing and cap are strained with waterproof rubber gasket 7 in Fig. 4 and cap 9, realizes water-proof function.
As shown in Figure 3, connector 2 is arranged in the groove 6 of housing side, in groove 6, fill up silicone grease and complete the sealing between connector 2 and housing 1, owing to not relying on waterproof apron, connector does not have interference fit while installing, can not cause these part wearing and tearing or damage because of repeated disassembled and assembled, improved whole maintainability, extended useful life, simultaneously, owing to need to rely on external force extruding cushion rubber to seal with waterproof apron, and the mounting means of connector (upper and lower covers cooperation) has been doomed two sides and cannot have well been pushed waterproof apron.Use instead after silicone grease sealing, not only strengthened water resistance,, also reduced because the problem that after variations in temperature and long-time use, the aging sealing of bringing of waterproof apron weakens meanwhile.
As shown in FIG. 2 and 3, after connector 2 has assembled on housing 1, the upper limb opening part of housing has formed an anti-horizontal plane 3 of annular being in completely in same level, this anti-horizontal plane is after the cap 9 that is embedded with waterproof rubber gasket 7 covers, waterproof rubber gasket 7 is subject to the extruding of housing upper limb, two complete planes of cap edge, fit tightly between two planes, realize water-proof function.
It is tightr for housing is coordinated with cap, in Fig. 5, housing 1 coordinates part with being connected of cap 9, cap 9 is provided with annular jut, on this jut and housing 1, the groove part of annular just in time agrees with mutually, has played spacing effect, guarantees that the waterproof apron 7 of inlaying in cap is subject to the extruding of the arch part of housing accurately, produce deformation, reach good sealing effectiveness.
Four jiaos that are positioned at cap 1 inner chamber are provided with the PCB fixed leg of circuit board 4 stretching out downwards, and it is just in time pushed down inner pcb board fix.Owing to having abandoned the fixed form of screw screw in the past, greatly facilitate the installation and removal of PCB circuit board.Meanwhile, fixed leg also becomes the support column of cap after installation, has strengthened the structural strength of cap.
